I have achieved the fail over using keepalived but not sure how can we replicate the data from one server to other seamlessly and have them in sync with each other. My prime requirement for this project is end user should not notice the fail over and replicated copy of data should be available on the secondary as well.
View 3 Replies View RelatedI have a weird performance issue with a centos 5 running a nfs server and a rh8 client. I think the fact that it is rh8 client should be downplayed. It is just that with rh8 client the performance degradation seems more clear. See test details below OS in server is Centos 5 x86_64 kernel 2.6.18-92.1.22.el5
1Gb connection between machines File to test over NFS is a 1GB file. First of all I wanted to measure how the network alone performs while using NFS. So in the server side I run a "cat" command on the 1GB file to /dev/null. Please note that the disk read speed is about 98MBs. At this point the file system has the 1GB file cached in memory. In the client side a "cat" on the same file gives me a speed of about 113MBs. It seems then that the bottleneck in this instance is the network and it is very close to nominal speed. So the network performance is really good. (BTW I know that the server got that file from cache because a vmstat or iostat shows no disk activity.)
The second test is reading from disk with no caching involve. In the server I flushed the 1GB file from the memory. For instance by reading another 5GB file and I repeat the same thing as above in the client (a cat on the 1GB file). Now, the server has to go to disk.(vmstat or iostat shows the disk activity). However the performance, now, is about 20MBs, I was expecting something closer so 90MBs. (since the reading speed in the server in the first test showed 98MBs).
This second test was repeated for ext2, ext3, xfs with no significant differences. A similar test using a RH8 NFS server and client gets me close to 60MBs for a 1GB file not cache by the file system in the serverSince network speeds and disk read speeds are not the bottlenecks ... what or where is the limiting factor then?

I have a remote ftp serwer, witch many of disks, something SATA, some IDE... There are ext3 filesystems. And a lot of files and direcotories/subdirectories. Tell me, which filesystem is the best for serwer like this? I'm not interesting on efficiency... The most important thing is failure-free. On ext3 sometimes is problem witch 'dirty' filesystem, in that case I must handy run e2fsck to fix this. Is any option to automate this, or any power-down proof filesystem?

View 3 Replies View RelatedI have a 2TB file-system and when the machine reboots it fails the fsck, halts and goes into maintenance mode.Stats: I have have RHEL 5, 2.6.18 kernel, the file-system is an ext3. The file-system is on an EMC AX4 connected with fiber channel HBA.So far my reading tells me this should work because under 2.6 4TB is OK. Any ideas why this fails?If I take it out of the fstab file and mount it manually the boot is OK and the file-system behaves well. I can change the fsck check option in the fstab to 0 but I don't think I should have too. Everything I read says that 2TB ext3 file-systems are OK.

I have two web servers. One is active and one is in reserve. I keep the user data (web pages) in sync by running rsync every 10 minutes or so. This copies any changes from the active machine to the reserve machine. But, it's slow, only gets changes every 10 minutes, bogs down the disk, does strange things to files that are changing during the rsync process etc...
I want something that will automatically copy any changes from the active server to the reserve server as they are made. IE I hit 'save' on the active server, it copies the file to the reserve server. Simple!
I've been looking around and I see GFS which is really vastly more complicated than I need. I'm happy with read-only access on the reserve host, so I don't need distributed lock management.
I could theoretically implement this by setting inotify watchers on every file and running an SCP or rsync command when a file gets saved. So, it can't be that hard.
I do not need a true networked file system, as in something I mount over the network. I just want something to keep my disks in sync.
Blue sky thinking at the moment:I have a number of file servers, each at different sites. I would like to be able to make these appear as one, so that files on any server can be accessed from any site, and the user doesn't even see there are multiple servers.Obviously, the internet is slow, especially the upload speeds. So when a file is written the write ought to go to the server on the client's LAN - even if it was previously on another of the servers.However, for robustness, some sort of background mirroring is also wanted. If all the servers were left on and connected, they eventually end up all in sync. But this mirroring needs to be mindful of bandwidth usage; if someone writes a big file to their local server, copying that to the other servers can't interfere with normal internet usage.I think UnionFS or similar might be able to handle the unioning side, but not the mirroring stuff.

I need a webserver (LAMP) running inside a virtual machine (#1) running as a service (#2) in headless mode (#3) with part or the whole file system encrypted (#4).The virtual machine will be started with no user intervention and provide access to a web application for users in the host machine. Points #1,#2 and #3 are checked and proved to be working fine with Sun VirtualBox, so my question is for #4:Can I encrypt all of the file system and still access the webserver (using a browser) or will GRUB ask me for a password?If encrypting all of the file system is not an option, can I encrypt only /home and /var/www? Will Apache/PHP be able to use files in /home or /var/www without asking for a password or mounting these partitions manually?
